Ancora tracks in the UCSC and Ensembl genome browsers. Genome browser views of region around the human SHOX2 gene. Added tracks show locations and densities for HCNEs detected at similarity thresholds of 95% in the mouse comparison and 70% in the zebrafish comparison. (a) UCSC, same region as in Figure 2. (b) Ensembl, displaying 1 Mb (the maximum allowed size in ContigView) of the same region. Additional tracks from Ensembl show conserved elements ('Conservation') and transcripts ('Ensembl trans.').
